Telephone companies are finding themselves confronted with a very basic problem: multiple networks. The solution that was devised is a unique new network for the future that will replace the entire telephone system and all the specialized networks with a unique completed network for all types of transport of information. This new network will support enormous rhythm of data compared to all the existing networks and services, and will render possible the offer of a large variety of new services. The new service network for a wide region is called Digital Network of Completed Services of Wide Area broadband integrated services digital network (B-ISDN). The technological infrastructure that renders it feasible is called asynchronous way of transport: asynchronous transfer mode (ATM) because the transmission is not modern; that is, attached in a being first clock.

Key Terms in this Chapter

WAN: Wide area network.

LAN: Local area network.

Safety: The state of being safe, the condition of being protected against physical, social, spiritual, financial, political, emotional, occupational, psychological, or other types or consequences of failure, damage, error, accidents, harm, or any other event that could be considered undesirable.

Asynchronous Transfer Mode (ATM): A cell relay network protocol that encodes data traffic into small fixed-sized (53 byte; 48 bytes of data; and 5 bytes of header information) cells instead of variable sized packets (sometimes known as frames) as in packet-switched networks (e.g., Internet Protocol or Ethernet).

Data T ransmission: The conveyance of any kind of information from one space to another.

Computer Networking: The scientific and engineering discipline concerned with communication between computer systems.

Transmission (telecommunications): The act of transmitting electrical messages.
